Here the sporangia are irregular in shape, owing to their contraction after ripeness and during fossilization.
sporangia sessile, round, whitish, covered with an ashy-gray scurf.
The clusters of the sporangia are covered with small indusia which are slightly notched.
In these the sporangia are large and the ring (r) rudimentary.
The sporangia are so crowded that many are choked off below, never reach the top of the thalium.
The spores are generally formed in special spore-capsules (sporangia).
sporangia globose or ovoid to ellipsoid or oblong, erect or sometimes inclined or even nodding.
These spores are collected in spore-cases or sporangia (Fig. 7).
The tips of the sporophylls overlapped and afforded protection to the sporangia.
The sporangia have very short stalks, and are not provided with an annulus at all.
sporangium spo·ran·gi·um (spə-rān'jē-əm)
n. pl. spo·ran·gi·a (-jē-ə)
A cell within a fungus in which asexual spores are produced by progressive cleavage.
